Understanding Phenol Adsorption Mechanisms on Activated Carbons
The interactions between phenol molecules and activated carbons were investigated in order to understand the adsorption mechanism of this aromatic compound. A series of activated carbons with varied chemical composition but similar porous features were synthesized and submitted to phenol exposure from aqueous phase, followed by thermogravimetric analysis and identification of the desorbed speci...
متن کاملPreparation, characterization and phenol adsorption capacity of activated carbons from African beech wood sawdust
In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. The d...
متن کاملImproved phenol adsorption on carbons after mild temperature steam reactivation.
The purpose of this work is to explore steam reactivation at moderate temperatures of activated carbon exhausted with phenol, a highly toxic compound frequently present in industrial wastewater. The spent carbon was treated with steam at various temperatures (450, 600 and 850 degrees C) and times (from 5 to 60 min). Promising results were obtained by applying moderate temperatures and times. Wh...
